[Bug 849414] Re: plymouthd crashed with SIGSEGV in ply_event_loop_process_pending_events()

[James Hunt]

I've now written a plymouth C client that fires semi-random plymouth
commands to plymouthd continuously (with random delays) and have run
multiple instances of this in an attempt to force the bug and plymouthd
still fails to crash.

We really need a failing /var/log/plymouth-debug.log (or a failing
valgrind.log) if anyone can obtain one...?
